Abstract: A microstructure arrangement having a substrate; a set of pillars having a cross section area in the range of 10 ?m2 to 160,000 ?m2 and a pitch in the range of 20 ?m to 1000 ?m. The set of pillars can be on a set of pillars having a cross section area less than that of the pillars. The set of pillars can be defined by pillars each having a cross section width from 0.5 ?m to 100 ?m and a pitch in the range of 1 ?m to 200 ?m; and, wherein the set of pillars can be configured to cooperate to have a physical property of a grip force in excess of 50.0 N with a contact area of 25% or less, as determined by the friction testing method.

Abstract: A substrate having an undulating surface forming a series of rounded peaks and valleys that produce a continuously curving surface across at least a portion of the substrate. The undulating surface defines a first set of micro features. A second set of micro features molded on the first set of micro features. The substrate is a compression molded polymeric material in which the first and second sets of micro features are formed on the substrate during a single molding step, and wherein the first and second sets of micro features cooperate to increase the surface area and affect at least one of adhesion, friction, hydrophilicity and hydrophobicity of the substrate.
